腹腔镜胆囊切除术与开腹胆囊切除术免疫功能的比较

胆囊结石病人40例，择期手术分别行腹腔镜胆囊切除术（LC）和开腹胆囊切除术（LC）各20例。测定手术前后血清白细胞介素-6（I－6），C-反应蛋白及外周血T淋巴细胞亚群改变，比较二种不同胆囊切除手术方式的手术创伤程度对机体免疫功能的影响。结果OC组术后12、24及48小时血清IL－6和CRP含量分别高于LC组（P＜0．05）。两组术后24小时CD4、CD4及CD4／CD8百分率有显著差异（P<0.05），72小时CD4、CD8及CD4／CD8比值相近（P＞0.05）。两组平均手术时间和切口长度有显著差异（P<0．05）。结果表明，OC手术创伤大，术后免疫功能改变明显，LC切口小，平均手术时间短是术后血清IL－6和CRP含量低及外周血T淋巴细胞亚群无明显改变的主要原因。

Inflammatory response in open and laparoscopic cholecystectomy

The modifications of IL-6. CRP, ceruloplasmin, alpha 1 antitrypsin, fibrinogen, transferrin, albumin and leukocytes counts have been evaluated after traditional open cholecystectomy (OC) or laparoscopic cholecystectomy (LC). Forty-two patients were included in this study, 20 underwent to OC and 22 underwent to LC. Serum samples were performed before surgery and at distance of 6, 24, 48 and 168 hours. The results show a more significant increase in acute phase inflammatory response after OC compared with LC as attested by highest values of leukocytosis, IL-6, CRP, fibrinogen and alpha 1 antitrypsin and lower levels of albumin. In conclusion, after LC, the phase acute response is attenuate and it can explain the reduced period of convalescence of patients treated with LC.     

Systemic inflammation and immune response after laparotomy vs laparoscopy in patients with acute cholecystitis,complicated by peritonitis

AIM: To evaluate acute cholecystitis, complicated by peritonitis, acute phase response and immunological status in patients treated by laparoscopic or open approach. METHODS: From January 2002 to May 2012, we conducted a prospective randomized study on 45 consecutive patients (27 women, 18 men; mean age 58 years). These subjects were taken from a total of 681 patients who were hospitalised presenting similar preoperative findings: acute upper abdominal pain with tenderness, involuntary guarding under the right hypochondrium and/or in the flank; fever higher than 38 ℃, leukocytosis greater than 10 × 10 9 /L or both, and ultrasonographic evidence of calculous cholecystitis possibly complicated by peritonitis. These patients had undergone cholecystectomy for acute calculous cholecystitis,complicated by bile peritonitis. Randomly, 23 patients were assigned to laparoscopic cholecystectomy (LC), and 22 patients to open cholecystectomy (OC). Blood samples were collected from all patients before operation and at days 1, 3 and 6 after surgery. Serum bacteraemia, endotoxaemia, white blood cells (WBCs), WBC subpopulations, human leukocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin-1 (IL-1) and IL-6, and C-reactive protein (CRP) were measured at 0, 30, 60, 90, 120 and 180 min, at 4, 6, 12, 24 h, and then daily (8 A.M.) until post-operative day 6.RESULTS: The two groups were comparable in the severity of peritoneal contamination as indicated by the viable bacterial count (open group = 90% of positive cultures vs laparoscopic group = 87%) and endotoxin level (open group = 33.21 ± 6.32 pg/mL vs laparoscopic group = 35.02 ± 7.23 pg/mL). Four subjects in the OC group (18.1%) and 1 subject (4.3%) in the LC group (P < 0.05) developed intra-abdominal abscess. Severe leukocytosis (range 15.8-19.6/mL) was observed only after OC but not after LC, mostly due to an increase in neutrophils (days 1 and 3, P < 0.05). This value returned to the normal range within 3-4 d after LC and 5-7 d after OC. Other WBC types and lymphocyte subpopulations showed no significant variation. On the first day after surgery, a statistically significant difference was observed in HLA-DR expression between LC (13.0 ± 5.2) and OC (6.0 ± 4.2) (P < 0.05). A statistically significant change in plasma elastase concentration was recorded post-operatively at days 1, 3, and 6 in patients from the OC group when compared to the LC group (P < 0.05). In the OC group, the serum levels of IL-1 and IL-6 began to increase considerably from the first to the sixth hour after surgery. In the LC group, the increase of serum IL-1 and IL-6 levels was delayed and the peak values were notably lower than those in the OC group. Significant differences between the groups, for these two cytokines, were observed from the second to the twenty-fourth hour (P < 0.05) after surgery. The mean values of serum CRP in the LC group on post-operative days (1 and 3) were also lower than those in the OC group (P < 0.05). Systemic concentration of endotoxin was higher in the OC group at all intra-operative sampling times, but reached significance only when the gallbladder was removed (OC group = 36.81 ± 6.4 ρg/mLvs LC group = 16.74 ± 4.1 ρg/mL, P < 0.05). One hour after surgery, microbiological analysis of blood cultures detected 7 different bacterial species after laparotomy, and 4 species after laparoscopy (P < 0.05). CONCLUSION: OC increased the incidence of bacteraemia, endotoxaemia and systemic inflammation compared with LC and caused lower transient immunological defense, leading to enhanced sepsis in the patients examined.

Effect of open and laparoscopic surgery on cellular immunity in a swine model

Immune suppression associated with trauma has been demonstrated to be proportional to the magnitude of injury. Laparoscopic surgery has been shown to produce a diminished stress response compared to open surgery. Postoperative immune function, specifically cellular immunity, may be better preserved after laparoscopic surgery compared to open surgery. The aim of this study was to examine the effect of open versus laparoscopic surgery on cellular immunity in a swine model. Twenty domestic female pigs were randomly selected for laparoscopic cholecystectomy (LC) or open cholecystectomy (OC). Cellular immune functions were evaluated with delayed-type hypersensitivity (DTH) skin test and serial phytohemoagglutinin (PHA)-induced T-cell proliferation of the peripheral blood. There was a significant reduction in PHA-induced T-cell proliferation in both LC and OC groups on days 1 and 3 compared to preoperative values (p < 0.05). The reduction of mitogen-induced T-cell proliferation after LC was significantly less than after OC on day 1 (p = 0.03). The mean DTH reaction was 29.7 +/- 3.7 mm2 in the LC group compared to 13.9 +/- 1.2 mm2 in the OC group (p < 0.001). There was no difference in postoperative white blood count values between the two groups. Suppression of cellular immunity occurred after both LC and OC. The magnitude and duration of impaired cellular immunity after laparoscopic surgery was less than after open surgery as measured by T-cell proliferation and DTH response.     

腹腔镜结直肠癌手术对应激细胞因子 ET、IL-6及CRP的影响

目的:探讨腹腔镜结直肠癌手术对机体应激反应的影响。方法:选择2006年6月~2007年3月结直肠癌患者35例,分为腹腔镜组15例,开腹组20例。比较两组围手术期内皮素(ET)、白细胞介素-6(IL-6)、C-反应蛋白质(CRP)及相关临床指标的变化。结果:两组患者的性别、年龄、身高、体重、术后病理分期及手术方式差异无统计学意义(P>0.05),平均手术时间腹腔镜组长于开腹组(P<0.05);术中平均出血量开腹组多于腹腔镜组(P<0.05)。腹腔镜组术后第1天ET显著下降(P<0.05),术后第3天恢复至术前水平;开腹组手术前后ET无显著变化。两组术后未出现显著差异。两组患者术后IL-6和CRP均明显升高(P<0.01),且开腹组明显高于腹腔镜组(P<0.01),术后第5天腹腔镜组IL-6恢复至术前水平,但开腹组仍明显高于腹腔镜组(P<0.05)。术后第5天两组CRP仍显著高于术前水平(P<0.05;P<0.01),且开腹组高于腹腔镜组(P<0.05)。结论:腹腔镜结直肠癌手术对ET、IL-6和CRP的影响小,应激反应比开腹手术轻、强度低、持续时间短。
